To all whom it may concern:

Be it known that-I, BURNs H. MARsriALL, a citizen of the United States and resident of Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Toys, of which the following is a SPGClfiCZttlOIl.

My invention is a toy of that class comprising pneumatic bodies, and it consists'in the combinations, constructions and arrangements herein described and cla med.

An object of the invention is to provide a toycomprising an inflatable translucent body and means for associating the 1nflat-" able body with a light emitting element in such manner that the light emittingbelement may be disposed within the inflate 1e body and will illuminate the'latter.

Other objects and advantages will be apparent from the following description, considered in conjunction with the accompanying drawings, in which -Figure 1 is a perspective view showing a toy embodying the invention,

Figure 2 is a fragmentary side elevation of the toy,

Fi re 3 is a section along the line 3-3 of Figure 2, looking in the direction of the arrows, v

Figure 4 is a perspective view showing a modified form of toy embodying the invention,

Figure 5 is a perspective view showing a modified form of body which may be comprised in an embodiment of the invention,

Figure 6 is. a fragmentary perspective view showing the body exhibited in Figure 5 and Figure 7 is a view showing a tube adapted for use in inflating the inflatable body of the form of the device exhibited in Figure 6.

Referring now to the drawings and particularly to Figures 1 to 3 inclusive thereof, I show in Figure 1 an inflatable body 1 which may be made of thin rubber or like translucent impervious material and may be formed in the similitude of an elephant, as shown, or ma able form. The inflatable body 1 is provided with an opening, as at 2, from which a tubular boss 3 may extend outward although the provision of a tubular boss is not absolutely "essential to the operation of the device, as will presently appear.

A supporting body 4 conforms in cross sectional contour to the tubular boss 3 in have any other desir-' the opening 2. The cross sectional area of the supporting body 4 preferably is slightly greater than that of the opening 2 or of the tubular boss 3 at the juncture of the latter with the walls of theopening 2 so that 'an air tight connection will be provided between the supporting body 4 and the walls of the openin 2 when the supporting body 4.- is inserted in the boss 3 to such position that the inserted end of the supporting body 4 15 substantially flush with the inner end of the opening The supporting body 4 is made of a dielectric material and may be formed with a narrow annular flange 5 at its inner or insorted end to further insure a fluid tight connection between the supporting body and the; walls of the opening 2 and to prevent accidental displacement of the supporting body from the opening 2. In this connection, it will be understood that the inflatable body lis preferably made of a mate rial possessing considerable inherent elasticity so that the supporting body may be conveniently inserted in the tubular boss 3 to the position illustrated in Fig. l or be removed therefrom without precluding a fluid fit between the supporting body and the walls of the opening 2 when the supporting body is in the position shown in Figure 1.

The supporting body 4 is provided with a socket in its inner endadapted for entubular boss 3 in the position shown in Figure 1.' The terminals of the usual electrical connections of the socket and light bulb 6 extend from the outer end of the supporting body 4 as indicated at 7 and 8 respectively in Figure 2, these terminals preferably having the form of posts screw threaded for engagement with nuts 9, The terminals 10 and 11 respectively of a source of electric current supply, such as a dry cell 12, may be connected electrically with the electrical connections of the socket for the electric light bulb 6 by means of a. pair of rigid connectors 13, each of which has a laterall extending arm at its lower end pro- 'vide with an opening receiving one of the terminals 10 or 11 and a lateral arm at its upper end provided with an opening receiving the corresponding. terminal 11 or 8-.

DOOR GONCERQLLER.

Application filed Qcto-ber 26, 1823. Serial No. 670,880.

To all whom, it may concern Beit known that I, Fi a gicis J. Measure, a citizen of the United States, residing in the city of New York, borough, and county of Queens, in the. State of New York, have i vented a certain new and useful Improvement in Door Controllers, of which. the following is a specification,

The invention relates to mechanism for opening and closing doors and more particularly for operating elevator shaftway doors. 7

The object of the invention, is to provide a simple, easily operated door opening device for sliding doors which will close the door automatically when released, and opcrate quickly and quietly. Another important object is to provide means whereby the partly closed door is held against any attempt by persons on the corridor side to reopen it. A further object is .to provide means for disconnecting the device to allow the sliding door to be swung outwardly when required. Another important object is to proyide means whereby the controller can be easily and rel ably installed without requiring alterations in or special constructiou of the doorframe or shaft tov receive it.

"The invention. consists in, certain novel features. and details. of construction and arrangement by which the aboveand other objects are attained, to be hereinafter .described and claimed. 1

The accompanying drawings form-a part of the specification and show the invention as it has been carried out in, practice.

Figure 1 is an .eleyation showing a sliding shaftway-door equipped with. the improved controller, seen from the interior of the shaft.

The remaining figures are on a scale and show portions.

Figure 2 is an elevation, partly in ertical section, showing the keeper and its connections to the door, and the door-operating letter slidablyv received in such keeper.

Figure 3. is a transverse. section taken on the line 3.3 in Figure 2.

Figure 4 is a sectiontaken longitu ilinally i arger of the leyer and keeper, on the line 441 in Figures 2 and g.

Figure .5 isa horizontal section taken on the line 5-5" in Figure 2.

Figure 6 1s a s de. elevation of the fired bracket to which the lever is connecteda d other connected parts, partly in vertical secion- Figure 7 is a plan or top view of the bracket.

FigureS is a face view of the same.

Figure 9 is a transverse section taken on the line 9.9in Figure 6 Figure 10is a transverse section taken on the line 101O in. Figure 6.

Similar reference numerals indicate the same parts in all the figures.

The door 12 is suspended fron'i hangers 13 engaged with a horizontal track 14: and slides horizontally in the usual manner to open and close the elevator shaftway opening. The saddle or sill ofthe doorfraine is marked 15 and the j ambs or bucks 16.

At the lower corner of the doorfraine farthest from the door-opening, i secured the master bracket 17 fastened by screws at 19. to the buck 1.6, and having a horizontally projecting foot 18 similarly fastened to the. saddle 15 and is thus held firmly in position. Near theupper end of the verti cal portion 17 of the bracket is an outwardly projecting semicircular lug 20 in which is a centrally located pin 21 serving as a pivot for a bifurcatedarm 22the legs #3 of which inclose the lug 2.0 and are. mounted on the pin.

The body of the arm is iJ-shapct, see Figure 10, and has apartition or abutment 2-1 near the lowerend provided with an aperture. 25 through which extends chain 26 fastened at one end to a pin 9.? in the vertical reinforcing flanges 280.1 the bracket 17, and at the other to a rod. 29 standing inclosed in the arm 22; the rod is encircled by a helical compression spring 31 abutting at the lower end against the partition 2-11- and at the upper end againsta nut 32 on the screwthreaded outer end of the rod.

The chain 26 lies tanv entially to the curve of the lug 20 and, with the rod 29, is thus maintained axially in the arm as the latter is swung on the pin 21. The expausiveforce of the spring 31 tends to swing the arm outwardly and. downwariiiiy and the tension of the spring is adjusted by the nut :32.

Set transversely ofthe legs 23 below the chain 26 is a pin 33 to which is attached the plunger rod 34c of a checking cylinder pivotally connected at the lower end to the foot 18 of the bracket 17' and serving to retard the outward movement of thearm 22 as will be understood. The rapidity of the outward swing is varied as required by a flow-controlling screw '7 set in the upper head of the cylinder -and operating as usual.

Secured in the arm .22 and covering its open face is the door-operating lever 36 of which the arm 22 is a continuation; it is channel-shaped in cross-section with its closed face presen'tedto the shaftway side of the door 12. The channel form aflords the desired light but eminently stiff quality necessary in the lever.

' a trough-like hollow keeper 43 receiving and guiding the lever 36 extending slidably therethrough. Its flanges 44 and 45 project outwardly from the plate and 7 receive a cover 46 applied thereon, thus in closing the lever, the flanges 47 and 48 of which project inwardly as shown. The keeper 43 is slightly trian ular in shape and is arranged to be oscillated vertically on its stud 42 relatively to the lever 36 by a handle or pull 49 projecting from the lower end of the flange 45. Mounted on the interior. face of the flange I 43 of the lever, within the keeper and extending longitudinallyof the lever as far as may be required, is a narrow ratchet-bar 50 having its teeth presented upwardly and arranged to be engaged by the angular nose 1 of a dog 51, fixed upon theinner face of the keeper 43, when thelatter is in the depressed position shown in Figure 2, and to be disengaged when the keeper is lifted to the position shown in dotted lines in'the same fig ure'by the upward movement of the'handle 49. V

On the outer end of the stud 42 and lying between the ratchet-bar 50 and the face of the lever 36, is a guide-roller 52 having a diameter nearly equal tothe distance between the flanges 47 and 48 of the lever and serves with either of such flanges as may contact therewith in the sliding movements j of the leverthrough the keeper in lessen' the dog 51.

ing the friction, and 53 is a similar but smaller antifriction roller mounted on a pivot pin 54 011 the keeper, arranged to contact with the inner face'of the leverfiange 47 when the keeper in thrown to disengage The operation is as follows :-Assuming the door to be closed and locked by the engagement of the dog with a 1'atchet-tooth,as

shown by the full lines in Figure 2, and it is desired to open the door, the attendant on the elevator car, not shown, grasps the handle or -pull'49 and moves the keeper 43 upwardly at its lower end to free the dog 51 from the ratchet I 50, this ,inovement throws the roller 53 into contact with the flange 47 of the lever 36 and thus supports it with liberty to slide freely; a continued pull on the keeper in the direction to open.

the door slides the latter to the position shown in dotted lines in Figure 1 and exposes the door opening. In this swing of the lever to the approximately vertical po-' On releasing the pull on the keeper 43 the door will automatically close by the force of the spring 31 acting through the lever 36, the rapidity of the closing movement being governed by the restricted flow of the fluid in the checking cylinder. 1'

The release of the keeper permits it to drop by gravity and present'the dog 51 in position to engage the teeth of the ratchetbar 50; the dog on reaching the bar will ride idly'over the "teeth but in position to engage each in its passage. This arrangement precludes any reverse movement of the door and eifectually prevents reopening by anyone on the corridor side of the door, and when the door is completely closed it is securely locked by the dog against opening from suchside, thus avoiding the danger of accidents due to attempts to pass the partially closed door.

The plate 40 may be secured ing type. \Vith the tablet 37 and its separable connection to the plate by the boss 39 and removable bolt 41 the controller may i be disconnected from the door and the latter with its su tiport-ing portion be swung on hinges, not shown, into the corridor to afford the full opening from the corridorto the car in theusual manner.

The door may be openedrfroiu the corridor side when required under exceptional circumstances, by inserting a key or other turning such key vinthe direction to engage with'and lift thekeeper and thus free the dog 51 from the engaged tooth on the ratchet-bar 5 0, as will beunderstood.

The opening and closing movements of the parts are practically frictionless and noiseless, the rollers 52 and 53 insuring directly to the door 1f the latter be of the simple slida smooth easy traverse of the lever through the keeper.

By attaching the bracket 17 directly to i the saddle and buck the device is reliably held and the necessity for alterations and special provisions to permit installation are avoided, and as the mechanism occupies but little space such installation is greatly simplified with a corresponding reduction in cost.

The parts within the keeper and arm are concealed and protected, and the joints are constructed to avoid wear and insure stability and alinement. The, construction of the spring closing mechanism and manner of connecting the checking mechanism are such as to permit installation under all conditions.

The controller is simple, durable, efficient and. inexpensive, and the parts are easily accessible for inspection and repairs.

hilodifications may be made in the forms and proportions in adapting the controller to various types of doors and conditions of service, and parts of the invention may be used without the whole.
